Today is author J.K. Rowling’s 51st birthday! She’s celebrating with the opening of Harry Potter and the Cursed Child and the news that—sorry pals—she has finished writing about Harry Potter. This eighth, theatrical installment concludes his narrative.

“[Harry] goes on a very big journey during these two plays and then, yeah, I think we’re done,” she told Reuters. “This is the next generation, you know. So, I’m thrilled to see it realized so beautifully but, no, Harry is done now.”

The play premiered at London’s West End theater on Saturday, July 30 and is already sold out through May 2017. A collaborative effort from Rowling, playwright Jack Thorne, and director John Tiffany, we rejoin Harry at age 37 — an overtaxed Ministry of Magic employee with three children.

But if you’re blue, just remember: Fantastic Beasts and Where to Find Them, the film based on the Harry Potter spinoff book, opens in November 2016. And in April 2016, Universal Studios in Los Angeles unleashed a Harry Potter attraction, the second in the United States. This franchise is sturdy enough to satiate all Potter longings for years to come.
